how make crystal report faster in windows form application

Question

Hi i working on windows form application

I have created one crystal report . i have code in my button click like this:

SqlCommand cmdrslt = new SqlCommand("Staffwiserpt", con.connect);
cmdrslt.CommandType = CommandType.StoredProcedure;
cmdrslt.Parameters.Add("@startDate", SqlDbType.NVarChar, 50, ParameterDirection.Input).Value = frmdateval;
cmdrslt.Parameters.Add("@endDate", SqlDbType.NVarChar, 50, ParameterDirection.Input).Value = Todateval;
cmdrslt.Parameters.Add("@deptid", SqlDbType.Int).Value = deptid;
cmdrslt.Parameters.Add("@empid", SqlDbType.Int).Value = empid;
da.SelectCommand = cmdrslt;
da.Fill(ds);
Staffwisecrpt rpt = new Staffwisecrpt();
if ((ds.Tables(0).Rows.Count > 0)) {
    rpt.SetDataSource(ds.Tables(0));
    rpt.SetParameterValue("frmd", setparmstartd);
    rpt.SetParameterValue("tod", setparmendd);
    rpt.SetParameterValue("Dept", cmbdepartment.Text);
    rpt.SetParameterValue("Employename", cmbemployee.Text);

    CrystalReportViewer1.ReportSource = rpt;
} 
else {
    MessageBox.show("No Records found", MsgBoxStyle.Information);
    return;
}

but this is taking some time to show the crystal report..is there any other way to write this code for improving my crystal report performance..?
how about background worker ?? i can implement that to this code? any help is very appreciable?

Answer 1

Yes, you can use background worker, take a look at this LINK .

but the best thing is you must optimize your code or query before displaying it to crystal report.
